This module allows to create 2 and 3 dimensional Van Krevelen Diagrams. Prior, a sum formula must be asigned to a feature. This can be done, using the "Formula prediction" module (Peak list methods/Identification/Formula prediction). All possible feature characteristics can be plotted in a third dimension. The plot window has a toolbar on the right side. The first button changes the size of the blocks, the second toggle the background color between black and white, the third toggles the visibility of a grid and the fourth adds annotations for identified features.
A rainbow or monochrome color coded paint scale can be used for the third dimension. Depending on the dataset, a black background of the plot may result in a better contrast.
The contrast can be further improved by removing extremly high or low values from the paint scale. This can be achived using the "Range for z-axis scale" parameter. Features above the limit are displayed in magenta, features below the limit are displayed in black.
